A 52-year-old women underwent penetrating keratoplasty for total corneal opacity after healed microbial keratitis with an uneventful postoperative period until six months when she developed gross diminution of vision. During examination, she was detected to have a membrane in the anterior chamber, creating a double anterior chamber with a total cataract. The graft was clear, and sutures were intact. Anterior segment optical coherence tomography (OCT) showed the membrane in the anterior chamber crossing the graft host junction, suggesting this membrane to be retained host descemet membrane. This was confirmed on histopathological examination. Double rhexis (descemetorhexis and capsulorhexis) was performed with cataract removal and intraocular lens (IOL) implantation, and patient had good visual recovery postoperatively.
一名52岁女性在微生物性角膜炎愈合后因全角膜混浊接受了穿透性角膜移植术,术后恢复顺利,直到六个月时视力大幅下降。检查时,发现她前房有一层膜,形成了一个双前房并伴有完全性白内障。移植片清晰,缝线完整。眼前节光学相干断层扫描(OCT)显示前房内的膜穿过移植片与宿主的交界处,提示该膜为残留的宿主后弹力层。组织病理学检查证实了这一点。通过双重撕除术(后弹力层撕除和晶状体囊膜撕除)联合白内障摘除及人工晶状体(IOL)植入术,患者术后视力恢复良好。
